A good bit of work came in last week, so for the past week I’ve been spending most of my day hunched over my computer. Well, hunched and also staring at the wall.
That there is the latest and greatest in LED mini projector technology. Made by Aaxa, the P300 weighs less than 1.5 lbs., takes only 25 watts to operate, and has a native resolution of 1280×800. It puts out 300 lumens, which is plenty bright even in the daytime. It’s also the only short throw mini projector that has keystoning capability, a combination which makes it just about perfect for mounting in a van. Can you tell that I’m a projector geek? It’s leftover from my days working at a themed entertainment design firm—every project I worked on had at least three projectors.
Eventually, the projector will be the center of Gypsy’s entertainment system. For now, it’s my second display at my makeshift work station at my parents’ house. The picture makes it look kind of ghetto, but trust me, it’s cool.
As if the projector wasn’t enough for a “Hey, isn’t this cool?” post, check out the switch and the 12 volt socket that I wired up to the sink cabinet thingy. I’m not sure if I should call it a cabinet–it’s really more like a frame or a stand. The open sides are really helpful while I’m still getting everything installed. It makes for very easy access, and very little cursing. Highly recommend. I’ll put some kind of door or cover on it eventually, maybe. Anyway, the switch operates the water pump, and the light comes on when the switch is on. Ain’t it pretty?
Wiring up an illuminated switch can be kind of tricky. It took a good bit of brain power for me to figure it out, especially because I wanted to add the 12 volt socket to the same, uh, circuit or branch or whatever they’re called. Here’s what the back looks like.
Okay, yeah, the back looks ghetto.
Jef and I spent yesterday changing out most of the 1/0 cable and replacing it with 4/0—seriously heavy duty stuff. Why is it that whenever you buy cable or wire the people selling it always want to know what it’s for? Nosey. If I want to electrocute myself I should be able to do it in peace.
Here’s the comparison between 1/0 and 4/0 cable. 1/0 is spindly and feels very flexible compared to the 4/0.
Nearly everything that has gone into this project has been a hack of some sort. The P-trap under the sink, the combiner box, and the grey water tank, to name a few. Here’s one more. The switches really aren’t meant to accommodate 4/0 cable—the lugs are too big. So I took a rotary tool to the switch and cut away some of the plastic to make room for the lug. Ghetto. (Can you keep a secret? I also took a bandfile to some of the lugs on the 1/0 cable and shaved the edges down so that the lugs would fit in the fuse holders. Shhh … don’t tell the NEC on me.)
This morning we once again plugged in the induction cooktop, and the inverter didn’t complain once. Of course, there’s a couple of reasons why that might be—for one thing the batteries started off at a higher voltage—but the 4/0 cable upgrade certainly couldn’t have hurt. After running the inverter at 1300 watts for a good 5 minutes, the cables didn’t feel warm to the touch which makes them much, much safer than the old 1/0 cable. Very cool.
